tools: selftests: riscv: Fix compile warnings in mm tests
When building the mm tests with a riscv32 compiler, we see a range
of shift-count-overflow errors from shifting 1UL by more than 32 bits
in do_mmaps(). Since, the relevant code is only called from code that
is gated by `__riscv_xlen == 64`, we can just apply the same gating
to do_mmaps().
